Twig Templates : Include dynamic data when using set

Question

I'm trying to use the Encode Email plugin to encode email addresses.

The email addresses are dynamic so I need to include the output from the database when I'm using set.

This is their example that doesn't use dynamic info:

{% set email = "<a href='mailto:you@example.com'>Your Name</a>" %}
{{ email | rot13 }}

And this is what I've tried that doesn't work.

{% set email = "<a href='mailto:{{ contactInfo.contactEmail }}'>{{ contactInfo.contactEmail }}</a>" %}
{{ email | rot13 }}

Is there a way to include the dynamic variables into the set statement?

Answer 1

The main thing to remember about Twig... You never need to nest tags within other tags. So putting {{ }} within {% %} is never going to work.

To concatenate a string in Twig, use the ~ character...

{% set email = "<a href='mailto:" ~ contactInfo.contactEmail ~ "'>" ~ contactInfo.contactEmail ~ "</a>" %}

Answer 2

Another way to do this is to use the other set syntax:

{% set email %}
  <a href="mailto:{{ contactInfo.contactEmail }}">{{ contactInfo.contactEmail }}</a>
{% endset %}

Sometimes it is easier to read.
